I'm looking for a word to describe a computer that's not a server. I know that in some contexts the opposite may be "client", but that implies the ability to form a network connection to a server, which is not necessary in my context. It can just be a standalone computer or any computer which does not run a server operating system.
I'm also looking for the opposite to "server operating system", for example, a word to describe all Windows operating systems that do not have "Server" in their name (Windows 2000, XP, Vista, 7, but not Windows Server 2000, 2003, 2008) – not necessarily restricted to Windows, though.
